iOS 崩溃报告 SKProductsRequest

Question

有人可以证实我的想法，即由于 SKProductsRequestDelegate 仍在分配，但代码本身并未分配，因此会生成以下崩溃报告吗？即 VC 已关闭？

StoreKit: __34-[SKProductsRequest _handleReply:]_block_invoke + 442

Exception Type:  EXC_BAD_ACCESS (SIGSEGV)
Exception Subtype: KERN_INVALID_ADDRESS at 0x41682340

如果我的想法是正确的，我可以通过调用来解决这个问题:-

request.delegate = nil;
[request cancel];
request = nil;

如果我错了，有人可以为我提供更多信息吗？

谢谢。

引用，我添加以下代码确实解决了这个问题。

request.delegate = nil;
[request cancel];
request = nil;
